After six weeks of exciting labor and solicitude, during which his sleep and his rations were always delayed till exhaustion overpowered him, and then cut down below half the normal standard, he wakes one morning from a slumber heavy as death into a state of the most awful vigilance his mind can conceive of. He even doubts for some moments whether he shall ever sleep again, and in the agony of that strange, wild suspicion, a cold sweat breaks out over him from head to foot. Waking from the most utter unconsciousness possible to a wide-awake state like having the top of one's skull suddenly lifted off by some surgeon Asmodeus, and the noonday sun poured into every cranny of his brain, he suffers a shock compared with which any galvanic battery, not fatal, gives but a gentle tap. The suddenness of the transition--no gentle fading out of half-remembered dreams, no slow lifting of lids, no pleasant uncertainty of time and place gradually replacing itself by dawning outlines of familiar chair and window frame and cornice--the leap from absolute nonentity into a glaring, staring world--for a moment almost unsettles Mr. Edgerton's reason. Then the fear for his sanity passes and a strange horror of approaching death takes its room. His pulse at the instant of waking throbs like a trip-hammer; an instant more and it intermits. Then it begins again at the old pace. He snatches up his watch from the bureau with a trembling hand and counts--the beat is 130 a minute. Again it stops; again it begins; but now little by little growing faster and threadier until it runs so swiftly yet so thinly as to feel under his finger like some continuous strand of gossamer drawn through the artery. His feet and hands grow deadly cold. He seems to feel his blood trickling feebly back to his heart from every portion of his body. He catches a hurried look at the glass--he sees a dreadful spectre with bistre rings around the eyelids, an ashen face, leaden lips, and great, mournful, hollow, desolate eyes. Then his pulse stops altogether; his lungs cease their involuntary action; and with a sense of inconceivable terror paralyzing the very effort he now feels it vital to make, he puts them under voluntary control and makes each separate inspiration by an effort as conscious as working a bellows. I doubt not that many men have died just at this place through absolute lack of will to continue such effort. Then the metaphorical paralysis of fear is seconded by the simulation of a literal one, extending through the limbs of one side or both; the sufferer reels, feeling one foot fail him--tries to revolve one arm like a windmill, that he may restore his circulation, and that arm for some instants hangs powerless. Presently, with one tremendous concentration of will, his brain shouts down an order to the rebellious member--it stirs with sullen reluctance--it moves an inch--and then it breaks from the prison of its waking nightmare.
